Deployable Nanoelectromechanical Bound States in the Continuum Enabled by GHz Lamb Wave Phononic Crystals on LiNbO3 Thin Films
Sheng-Nan Liang, Zhen-Hui Qin, Shu-Mao Wu +3
Bound states in the continuum (BICs) are a fascinating class of eigenstates that trap energy within the continuum, enabling breakthroughs in ultra-low-threshold lasing, high-Q sens…
Boundary-induced helical bulk acoustic transport in LiNbO3 thin films
Zhe Li, Zhen-Hui Qin, Shu-Mao Wu +10
We experimentally demonstrate boundary-induced helical bulk states (BI-HBSs) for RF acoustic transport in LiNbO3 thin-film phononic crystals (approximately 175-200 MHz). A boundary…
K-band LiNbO3 A3 Lamb-wave Resonators with Sub-wavelength Through-holes
Shu-Mao Wu, Hao Yan, Chen-Bei Hao +3
Addressing critical challenges in Lamb wave resonators, this paper presents the first validation of resonators incorporating sub-wavelength through-holes. Using the A3 mode resonat…
Double-layer Thin-film LiNbO3 Longitudinally Excited Shear Wave Resonators with Ultra-large Electromechanical Coupling Coefficient and Spurious-Free Performance
Zhen-Hui Qin, Shu-Mao Wu, Chen-Bei Hao +4
This work proposes a double-layer thin-film lithium niobate (LiNbO3) longitudinally excited shear wave resonator with a theoretical electromechanical coupling coefficient exceeding…
